Hi Adam and Benjamin,

Regarding the citation of RFC 8259, in the Introduction, using the JSON format as specified in RFC 8259 may actually cause backwards compatibility issues with RFC7285 that uses the JSON format specified in RFC7159. Would it be OK to cite 7159 in the Introduction and add the paragraph below in section 2.2.2 “Compatibility with legacy ALTO Clients" ?

Thanks,
Sabine

<t>Last, for backwards compatibility with <xref target="RFC7285"/>, 
          this extension encodes its requests and responses using the JSON 
          Data Interchange Format specified in <xref target="RFC7159"/>. 
          The latter has been obsoleted by <xref target="RFC8259"/>, 
          that among others makes UTF-8 mandatory for text encoding to 
          improve interoperability. Therefore, Clients and Servers supporting 
          ALTO Calendars SHOULD use UTF-8 for text encoding while still being able to 
          successfully read texts in other encodings such as UTF-16 and UTF-32.</t>

That seems a reasonable approach. Thanks!
